- Referring to
FIG. 1 andFIG. 2 , in the illustrated embodiment, the lawncare apparatus is a hand push lawnmower. The lawncare apparatus includes amain body 1, a first pair ofwheels 11 and a second pair ofwheels 12 supporting themain body 1, a cutting blade disposed in themain body 1, a motor driving the cutting blade, and anoperating arm 2 connected to the first end (rear end) of themain body 1. The first pair ofwheels 11 and the second pair ofwheels 12 are disposed respectively at the second end (front end) and the first end (rear end) of themain body 1. Theoperating arm 2 is pivotally connected to the rear end of themain body 1 by apivot shaft 22 and positioned above the second pair ofwheels 12. The front end of themain body 1, which is away from theoperating arm 2, includes anelongated handle 13. In the illustrated embodiment theelongated handle 13 is substantially cylinder-shaped and includes an axis Z2 along the longitude direction. Theoperating arm 2 includes acylindrical gripping portion 23 and can be folded to a folded position, and thecylindrical gripping portion 23 includes an axial central line Z1. - When the operating arm is at the folded position and the first pair of
wheels 11 and the second pair ofwheels 12 both contact the horizontal surface F, if thegripping portion 23 is above thehandle 13, the distance d1 in the vertical direction between the axial central line Z1 and the axis Z2 along the longitude direction is greater than the sum of the radius of thegripping portion 23 and the radius of the cylinder-shaped handle 13, and the distance d1 is less than 5 cm. For example, the diameters of the grippingportion 23 and the cylinder-shaped handle 13 are both 1.5 cm, then the distance d1 is at least greater than 1.5 cm. Preferably, the distance d1 is 3 cm, and a distance d2 in the horizontal direction between the axial central line Z1 and the axis Z2 is also less than 5 cm, and in the illustrated embodiment, the distance d2 is preferably 0.5 cm. Therefore, when theoperating arm 2 is at the folded position, the user can grip both thegripping portion 23 and the cylinder-shaped handle 13 conveniently. - Additionally, in an alternative embodiment, to allow the user to grip both the
gripping portion 23 and the cylinder-shaped handle 13 more conveniently, the internal profile of thegripping portion 23 is mated with the external profile of the cylinder-shaped handle 13, such that when theoperation arm 2 is at the folded position, the outer surface of the grippingportion 23 and the cylinder-shaped handle 13 contact with each other. At this time, thegripping portion 23 and the cylinder-shaped handle 13 can lie in a horizontal plane, the distance d2 in the horizontal direction between the axial central line Z1 and the axis Z2 is larger than the sum of the radius of thegripping portion 23 and the radius of the cylinder-shaped handle 13, and the distance d1 is zero. It should be noted that the external profile of thegripping portion 23 may be designed to mate with the internal profile of the cylinder-shaped handle 13. - To allow the user to grip both the
gripping portion 23 and the cylinder-shaped handle 13 more stably, a clip K is disposed on thehandle 13. When the operation arm is at the folded position, the clip K is engaged with thecylindrical gripping portion 23. - Further, in the illustrated embodiment, the
operating arm 2 is extendable, and a safety switch assembly 240 is disposed in theoperating arm 2, theoperating arm 2 includes aninner pipe 25 and anouter pipe 21, theouter pipe 21 is rotatably connected to the rear end of themain body 1 by thepivot shaft 22, and the end of theouter pipe 21 includes apipe sleeve 24. - Referring to
FIG. 3 , the safety switch assembly 240 is disposed in thesleeve pipe 24 and asafety shift structure 25 a is disposed in theinner pipe 25. The safety switch assembly 240 includes asafety switch 241 and atrigger assembly 242 configured to trigger thesafety switch 241 when thesafety shift structure 25 a of theinner pipe 25 is disengaged from a safety location and reset thesafety switch 241 when thesafety shift structure 25 a returns to the safety location. Thesafety switch 241 is electrically connected to a control circuit for controlling the motor in themain body 1. - In the embodiment, the
trigger assembly 242 is a contacting spring sheet. One end of the contacting spring sheet is connected to thesafety switch 241 and the other end is a free end. When theinner pipe 25 slides, the wall of theinner pipe 25 presses the contacting spring sheet to trigger thesafety switch 241. The contactingspring sheet 242 is formed with elasticity. When theinner pipe 25 slides, thesafety shift structure 25 a moves back to the safe position and, at this time, thesafety shift structure 25 a is within a receiving groove configured to accommodate the contacting spring sheet, and the contactingspring sheet 242 is out of outer force and will not trigger thesafety switch 241. - When the
inner pipe 25 is retracted into theouter pipe 21, thesafety shift structure 25 a leaves the safe position and the wall of theinner pipe 25 presses the contactingspring sheet 242 to trigger the safety switch. At this time, even during the transporting process, if the user operates the operating switch by mistake, the motor cannot be started, which can reduce the possibility of danger happening to the user. - Additionally, referring to
FIG. 2 again, when the lawnmower is at the using position, thefirst pair wheels 11 and thesecond pair wheels 12 are supported on the supporting surface F. If light is shining from a direction perpendicular to the supporting surface F, themain body 1 of the lawnmower projects a first orthographic projection on the supporting surface F. Referring toFIG. 4 , the lawnmower is at the storage position. When the lawnmower is stored, the lawnmower stands uprightly for storing in a storage room and theoperating arm 2 is folded and only thesecond wheels 2 are supported on the supporting surface F. For improving stability, a supportingportion 26 is disposed on themain body 1 for supporting on the supporting surface F, and the supporting portion can be integrated with or separated from themain body 1. In the same way, at this time if light is shining from a direction perpendicular to the supporting surface F, themain body 1 of the lawnmower projects a second orthographic projection on the supporting surface F. Since the width of the lawnmower at the using position is the same as that of the lawnmower at the storage position, and the distance D1 between thefirst pair wheels 11 and thesecond pair wheels 12 is larger than the distance D2 between the first pair ofwheels 11 and the supportingportion 26, the first orthographic projection area of the lawnmower at the using position is larger than the second orthographic projection area of the lawnmower at the storage position. - Referring to
FIG. 5 , when the lawnmower is changed from the using position to the obliquely pulled position, only thesecond pair wheels 12 contact the supporting surface and the hands of the user grip a pull portion which is preferably thecylindrical gripping portion 23. At this time, theoperating arm 2 is at the folded position, the distance of the grippingportion 23 relative to the supporting surface F is H; the distance of the grippingportion 23 relative to the point thesecond pairs wheels 12 contacting the supporting surface F is L, and the ratio of H to L may be 0.5˜1, preferably 0.8˜0.09, for meeting the needs of ergonomics. Therefore, when pulling the lawnmower, only part of the weight of the lawnmower is supported by the user, which makes the user feel more labor-saving. - From the above, the described lawncare apparatus can be pulled obliquely, and because of the structure mate relationship between the operating arm and the cylindrical gripping portion, the user can feel more comfortable during transporting and the pulling process is more stable, so that the volume of the lawncare apparatus during transporting is reduced and the operability of lawnmower pulling is improved. Since a safety switch mechanism is disposed on the operating arm, misoperation of the lawncare apparatus can be avoided and safety of pulling is improved.
- The general principle, primary features and advantages of the invention have been illustrated and described above. Those skilled in the art will appreciate that the foregoing embodiments are not intended to limit the invention in any form and technical implementations derived with equal substitutions or equivalent variations shall be considered as falling within the scope of the claimed invention.
